You appear to be running a SWT application. On macOS you must specify the -XstartOnFirstThread option when running the jar to run SWT correctly:
jar -XstartOnFirstThread -jar xxxx.jarSWT applications also have a native library which is different for each platform.
---------------
You have to add the correct SWT.jar to the classpath. You can download them here. (https://www.eclipse.org/swt/)
If you are deploying for Windows, you will have to bundle the swt jar for Windows (either 32bit or 64bit depending on the system).
If you want to create an application that runs on all platforms, have a look at this post:
